Effect of polymorphisms in the 5'-flanking sequence of MC1R on feather color in Taihang chickens.

ABSTRACT: MC1R plays an important role in the regulation of the formation, transfer, and deposition of melanin in animals and is important for determining coat color. Many studies have reported on single nucleotide polymorphisms (SNPs) in the coding sequence of MC1R. However, few studies have investigated the polymorphisms in the 5'-flanking sequence of MC1R. In this study, we sequenced 2000 bp of the 5'-flanking sequence of MC1R in 300 Taihang chickens with brown feathers (MTH) and 300 Taihang chickens with black feathers (HTH). The sequencing results showed that 4 SNPs (MC1R g.18838722 G > C, g.18838624 T > C, g.18838694 G > A, and g.18838624 C > T) were located in the 5'-flanking sequence of MC1R between the MTH and HTH groups. Association analysis showed that there was a significant correlation
